This invention relates to improvements in spools and containers therefor designed primarily for the reception and housing of surgical ad hesive tape but useful also, as to some ofits features, in connection with other types of tape. The device provided by the present invention consists of a flanged spool on which the tape is to be wound, a container or casing therefor for receiving and frlctionally interlocking with the 19 spool, so that the latter may be easily introduced and removed from it as required, and a cutting means movably attached to the flanges of the spool so thatit may be moved circumferential-11y to any desired position for the severing of sections or lengthsof the wound tape.

In the accompanying drawing- 7 Figure 1 is a perspective view of the spool (removed from its casing) and its cutting means, showing the manner in which the latter-is used for the severing of desired lengths of tape.

Figure 2 isa cross section of the spool and its casing, showing the tape wound upon the spool, the cutting" means thereon for severing 'tape lengths, and the means for frictionally locking :5 the spool to the casing. 7 V Figure 3-is an end view of thespool itself, partly broken away, also illustrating the manner. in which the cutter is used for the severing of tape lengths. 7 Figure 4 is a side view of the spool with its cutting means.

Figure 5 is a section thereof on the line B of Figur and Figure 6' is a side view, partly in section, showing the means for frictionally locking the spool to its casing.

In said drawing, i represents the flanged spool and 2 its casing; while 3 represents the cutter mounted on the spool.

The spool is of ordinary construction and when introduced into the casing 2 it is frictionally locked therein by engagement with inwardly punched projections l which frictionally enme the flanges of the spool]; the spool and easing Who-ingot sheet metals r d the spool readily utroduced into the casing into engagement with the projections 4 and "as readily removed from Q the casing when such removal is necessaryfor the unwinding of the tape on the spool. 1

The cutting means 3 consists of a carrier pro- 5 vided with a serrated cutting edge, and this carrier is mounted on the spool flanges by clips 5 extending around and under outwardly bent Lbeads 8 on the spool flanges. This connection between the cutter and the spool flanges maini0 tains the cutter in proper relation to the wound" tape and also permits the movement of the cutter to any desired position circumferentially of the flanges for the severing of any desired length of tape wound upon the spool barrel.' The cut 15 tel is provided with two such clips at'each of its 'ends so as to retainthe cutter firmly in position during the tearing or cutting of tape lengths.

It will be noted, as clearly shown in the drawing, particularly in Fig.5 thereof, that the cutter 20 is disposed betweemthe flanges and below the peripheries thereof with the clips extending upwardly for engagement with the flanges.

The clips necessarily pro] t beyond the beads 4 6 of the spool and for thisreason the casing is 25 "providedinteriorly with a recess 1 for the reception and passage of the cutter on'the introduce; a

tion ofthe spool into the casing and its removal therefrom. r

Islam 3 A spool for tape comprising a barrel for receiving a winding thereof, a pair of flanges at the ends of the barrel having outwardly turned beads at their edges, and a cutter carrier mounted .on the beads of the flanges and manually slidable 35 thereon to different cutting positions. around the .barrel and provided with means extending around and under the beads to hold the carrier in en-- gagement with the heralds between the flanges andfbelow the peripheries thereof, and a-casing 40 for ,said spool comprising a recess for the reception and of the cutter on the introduction of the spool into the casing and its removal therefrom.
